So I had a bit of a mad moment where I signed up to do the London to Brighton cycle ride. The night time version! Because I felt that cycling 54 miles in daylight wasn't hard enough, why not do it in the dark?

Please sponsor me - it's for a really good cause and there's the obvious comedy element that I never, ever do any exercise and that I don't actually own a bike.

As well as donations, any cycling advice you may want to pass on is also very welcome! I've already been warned about investing in cushioned pants....
